I have some vague memory that some of the controllers I tested when I
wrote the NetBSD code didn't interrupt, or maybe it was interrupt before
the status bits was set, so I avoided to use interrupts.

It should be trivial to break out the init code from the interrupt
routine and to use it in raattach() instead, try that and if it works
ask sms to do so instead. It's unlikely to break anything.
